My TW is a 2005. I bought it used with 1000 miles and the original tires on it. After the first ride(I am a trailrider) I determined that the front tire was in bad need of being changed to one that would stick better in the corners and not wash out so easily; I put on a Kenda K760 Trak Master 110/100-18 and it has done exactly what I needed to Ride most off road terrain here in Southern Idaho.
At first I was a little skeptical about the rear tire because early this Spring, when there was a bit of mud about, this tire seem to load up to easy. I solved that problem; stay out of the mud. Since that first experience I have put on another 500 miles on trails and found the stock tire to be an excellent tool for my needs. When the time comes, I will probably get another just like it unless I am convinced that a different one is even a better choice.
Happy Trails All
